Question

我想获得给定日期范围内的所有电影ID和名称。例如2012-02-01至2012-02-20应显示ids（1,2和3），它现在显示给定日期范围内的电影。

 movie{ id, name, start_date, end_date, visibility}

id   name  start_date  end_date     visibility
1    abc   2012-01-05   2012-02-10      1
2    xyz   2012-02-05   2012-02-25      1
3    cde   2012-02-19   2012-02-27      1
4    ghi   2012-03-01   2012-03-20      1

Answer 1

假设您要查找重叠，假设参数值位于名为params的表中：

SELECT *
  FROM movie AS m, params AS p
 WHERE CASE 
          WHEN m.start_date > p.start_date THEN m.start_date 
          ELSE p.start_date 
       END
       <
       CASE 
          WHEN m.end_date > p.end_date THEN p.end_date 
          ELSE m.end_date 
       END;

Answer 2

我们有两个区间：

FieldInterval := (start_date, end_date)

和TestInterval := (@StartDate, @EndDate)，定义为

@StartDate = '2012-02-01' 
@EndDate = '2012-02-20'

测试FieldInterval是否在TestInterval内：

SELECT id 
FROM movie 
WHERE @StartDate <= start_date      
  AND end_date <= @EndDate

测试TestInterval是否在FieldInterval内：

SELECT id 
FROM movie 
WHERE start_date <= @StartDate  
  AND @EndDate <= end_date

测试两个区间是否重叠：

SELECT id 
FROM movie 
WHERE start_date <= @EndDate 
  AND @StartDate <= end_date

Answer 3

select id  from movie  
where start_date between '2012-02-01' and '2012-02-20' 
and end_date between '2012-02-01' and '2012-02-20'
and start_date <= end_date;

Answer 4

我假设您想要将start_date和end_date放入2个参数的电影，对吗？

select id, name from movie
where @startDate < create_date and end_date< @endDate

如果您通知2012-02-01和2012-02-20，它将返回所有在该范围之间有start_date和end_date的电影

Answer 5

select id, name from `movie` where 
end_date >= '2012-01-05' and 
start_date <= '2012-01-20'

这对我有用，看起来很简单。
